Check for two things:
* Is the node in question an AsyncTreeNode? If so, you have to configure it with the correct loader (remember: applyLoader is set to false on the root)
* If you don't want the node to be an AsyncTreeNode, configure it with the appropriate node type (e.g. nodeType: "node").

Andreas.
